< Effect of embodiment 1 >
According to embodiment 1, the outdoor unit 101 of the air conditioning apparatus 100 includes the machine room 9. The outdoor unit 101 of the air conditioner 100 includes a compressor 105 disposed at the bottom in the machine room 9. The outdoor unit 101 of the air conditioner 100 includes a reactor 14 which is disposed in the machine room 9 at a height equal to or greater than the height of the compressor 105 and rectifies the current supplied to the compressor 105. The outdoor unit 101 of the air conditioner 100 has a height as high as the reactor 14, and surrounds the side insulator 21 of the compressor 105. The outdoor unit 101 of the air conditioner 100 includes an upper insulator 22 surrounding at least a part of the reactor 14 and placed on the side insulator 21.
According to this structure, the side insulator 21 is at a height up to the reactor 14 and surrounds the compressor 105. Further, the upper insulator 22 surrounds at least a part of the reactor 14 and is placed on the side insulator 21. Thereby, at least a part of the reactor 14 is surrounded by the side insulator 21 and the upper insulator 22 together with the compressor 105. Therefore, the electromagnetic sound generated by the reactor 14 can be suppressed together with the driving sound of the compressor 105. Further, it is not necessary to cover the lower side of the electric substrate 13 with a case made of a metal plate, and the machine chamber 9 is not limited to be narrow because there is no case. Further, since a case made of a metal plate is not used, the cost can be reduced. Therefore, while suppressing the electromagnetic sound of the reactor 14 together with the driving sound of the compressor 105, the space of the machine chamber 9 can be kept narrow, and the cost can be reduced.
According to embodiment 1, the upper insulator 22 covers at least a part of the upper surface of the reactor 14.
According to this structure, at least a part of the upper surface of the reactor 14 is surrounded by the side insulator 21 and the upper insulator 22 together with the compressor 105. Therefore, the electromagnetic sound generated by the reactor 14 is further suppressed together with the driving sound of the compressor 105. Further, the upper insulator 22 can suppress heat dissipation from the reactor 14 to the electrical substrate 13 disposed above.
According to embodiment 1, a connection terminal 14a to which wiring from the electric substrate 13 is connected is provided so as to protrude from the upper surface of the reactor 14. In the upper insulator 22, a cutout 22a is formed corresponding to the periphery of the connection terminal 14a. The upper insulator 22 combines the cut-out portion 22a with the periphery of the connection terminal 14a, and covers the upper surface of the reactor 14 except for the protruding connection terminal 14a.
According to this structure, the upper insulator 22 covers the portion other than the connection terminal 14a. Therefore, the electromagnetic sound generated by the reactor 14 can be further suppressed together with the driving sound of the compressor 105. Further, the upper insulator 22 can further suppress heat dissipation from the reactor 14 to the electrical substrate 13 disposed above.
According to embodiment 1, the upper insulator 22 completely covers the upper surface of the reactor 14.
According to this structure, the upper insulator 22 completely covers the upper surface of the reactor 14. Therefore, the electromagnetic sound generated by the reactor 14 can be shielded together with the driving sound of the compressor 105. In addition, the upper insulator 22 can block heat radiation from the reactor 14 to the electrical board 13 disposed above.
According to embodiment 1, the side insulator 21 has the same height of the upper end 21a except for the portion where the reactor 14 is disposed. The upper insulator 22 is placed on the upper end 21a of the side insulator 21 at the same height except for the location where the reactor 14 is disposed.
According to this structure, the upper insulator 22 can be stably placed on the side insulator 21. This improves the sound insulation performance of the side insulator 21 and the upper insulator 22. This can suppress electromagnetic noise generated by the reactor 14 together with the driving noise of the compressor 105.
According to embodiment 1, outdoor unit 101 of air conditioning apparatus 100 includes partition plate 10 that partitions the interior into machine chamber 9 and heat exchanger chamber 8. The reactor 14 is fixed to the partition board 10.
With this configuration, the installation step and the wiring step of the reactor 14 are completed before the casing 1 of the outdoor unit 101 is covered, and the outdoor unit 101 can be easily manufactured.
According to embodiment 1, the partition plate 10 has a cooling hole 10a as a cooling means in the back surface portion of the reactor 14 fixing portion.
With this configuration, the cooling hole 10a can cool the reactor 14 from the back surface. Thus, even if the reactor 14 generates heat in the space surrounded by the side insulator 21 and the upper insulator 22, the reactor 14 can be cooled without enclosing the heat.
According to embodiment 1, the cooling mechanism is a cooling hole 10a formed through the partition plate 10 in a region in the back surface portion of the fixed portion of the reactor 14.
According to this configuration, the reactor 14 can be cooled from the back side by the cooling holes 10a formed in the separator 10. Thus, even if the reactor 14 generates heat in the space surrounded by the side insulator 21 and the upper insulator 22, the reactor 14 can be cooled with a simple structure, and the heat is not confined.
According to embodiment 1, the partition plate 10 is bent at the bent portion 10b so as to protrude toward the machine room 9 side at the fixing portion of the reactor 14 in the ventilation direction a, and is formed as the flat portion 10c only at the fixing portion of the reactor 14.
According to this configuration, in order to perform heat exchange in outdoor unit 101, the wind flowing in ventilation direction a easily blows to reactor 14 at the bent portion of bent portion 10b of partition plate 10, that is, at the fixed portion of reactor 14. This allows the reactor 14 to be efficiently cooled by the wind flowing into the outdoor unit 101. In addition, since the separator 10 is formed as the flat portion 10c only at the fixing portion of the reactor 14, the reactor 14 can be easily fixed to the separator 10.
According to embodiment 1, the side sound insulator 21 is one sheet.
With this structure, the side insulator 21 can be simply configured.
According to embodiment 1, the side insulator 21 has an overlapping portion 21e in which both the inner end portion 21c and the outer end portion 21d are overlapped in a part of the side of the compressor 105.
According to this configuration, both the inner end 21c and the outer end 21d of the side insulator 21 overlap, and sound insulation performance can be improved.
According to embodiment 1, the upper insulator 22 is one sheet.
With this structure, the upper insulator 22 can be simply configured.
According to embodiment 1, at least one layer of the upper sound insulator 22 is composed of a rubber material.
